Should We Wait 300 Years for Clean Air in U.S. National Parks?

If you’ve been planning a visit to Yellowstone National Park, and are hoping for a perfectly clear, crisp day, you’ll have to wait awhile. Like 150 years or so.

You see, Yellowstone, like many of the United States' national parks, suffers from some pretty serious air pollution. According to the National Parks Conservation Association, at current rates of progress, it’s going to take until 2163 for Yellowstone to clear the haze and once again have natural air quality.

Yellowstone isn’t alone. The NPCA crunched the numbers of ten flagship national parks, and found some disappointing results. According to their research, natural air quality in these popular and prestigious parks wouldn’t be achieved until these dates:

  • North Cascades National Park (Washington) – 2276
  • Badlands National Park (South Dakota) – 2265
  • Voyagers National Park (Minnesota) – 2177
  • Yellowstone National Park (Wyoming/Montana/Idaho) – 2163
  • Theodore Roosevelt National Park (North Dakota) – 2158
  • Big Bend National Park (Texas) – 2155
  • Grand Canyon National Park (Arizona) – 2127
  • Black Canyon of the Gunnison National Park (Colorado) – 2119
  • Joshua Tree National Park (California) – 2106
  • Sequoia National Park (California) – 2096
